- A Mini-Doc for PSOUND.ARC
-
- I. Introduction
-
- This file is a small documentation file for the Perfect Sound sound editor
- contained therein. This file does not replace the full manual, which can
- be had (along with an update of the program itself and further information)
- from SunRize Inc. Ordering information can begotten from the program
- itself...Just go to the rightmost menu and select "About...".
-
- The program was made to interface with the Perfect Sound audio digitizer,
- copyright 1986 from SunRize Inc. The digitizer itself, along with a full
- Manual and an upgrade to the program, can also be ordered directly for
- a$79.00 charge (See above for ordering information). Enough..on to the how
- to use. This software also works with the FutureSound audio digitizer.
-
- II. Features of the program.
-
- The Perfect Sound editor can work with both IFF and non-IFF sampled sounds,
- and can play (and create) IFF-format instrument files. For full details on
- the IFF (Interchange File Format) format, see the IFF_SND_FORMAT file on
- this BBS. This text file will only deal with IFF where necessary.
-
- To load a sound, go to the File menu and select "Load". A requester will
- pop up and will default to df0: for sound files. If your sound files are
- in another drive or directory, then click in the box marked "Drawer" and
- enter the new directory at any time. Otherwise, click on the file you want
- to load, then click on the gadget marked "Load".
-
- The editor (depending on memory limitations) may have up to 15 sounds
- loaded at any one time. You will see the names of available sounds (which
- is the same as the filename) will be shown on screen at all times.
- Clicking on the name of a sound is the same as clicking on the gadget
- marked "Play Sample" in the lower right-hand corner of the screen.
-
- a. Gadgets and tools onscreen
-
- There are 5 base gadgets onscreen at any one time. They are marked:
-
- 1. Pos'n
- 2. Start
- 3. End
- 4. Play Range
- 5. Play Sample
-
- The use of these are as follows:
-
- 1. Pos'n: This one, which means position, is used to define where in the
- sound any inserting will be done. Otherwise, this gadget has no effect.
-
- 2. Start: This gadget defines the start of an edit range, an edit range
- being that part of a sound where most editing takes place. If you have
- ever used a word processor, this is much like "block Start" on a WP. The
- "PlayRange" gadget will begin playing the sound starting from this point in
- it. There is a numeric indicator of the position of this slider gadget in
- the bottom of the screen. The arrows to the right of this gadget will
- raise/lower the value of this gadget by 1 for fine-tuning purposes. Is
- also used to define the repeating part of an instrument when an instrument
- is being defined. This has no other effects.
-
- 3. End: This gadget defines the end of the range, and is similar to the
- "Block End" on a regular word processor. The arrows at the end of this
- gadget are for fine-tuning, as they are for the Start gadget. No other
- effects.
-
- 4. Play Range: This will play the range defined for the current sound.
-
- 5. Play Sample: Plays the entire sound, regardless of the Start and
- Endmarkers.
-
- b. Menu Items
-
- All menu items are active, save for the "Digitize" menu. Do NOT use this
- menu unless you have the digitizer, or you will lock the system with noway
- to get out of it, as the program looks for a signal that never comes.
- Other menu items are: Edit, Special, File (explained above.) The useful
- menus are explained below, save for "File", which is self-explanatory.
-
- 1. Edit
-
- The Edit menu's functions (most of them) will operate on
- thecurrently-selected range. These functions are:
-
- a. Delete a range: Simple enough, delete the currently-defined range.
-
- b. Delete sample: Delete entire sample from memory
-
- c. Insert marked range: This will copy part of one sample into another or
- even into the same sample. First, select the range to be copied from.
- Then, select the sound to copy the range into. Set the pos'n gadget to the
- place in the sound you want the other sound to be inserted into. Then,
- select this menu item. Click on the sound you want to insert FROM. The
- marked range from that sound will then be copied to the current sound,
- starting at the place marked by the pos'n gadget.
-
- d. Copy Range to new Slot: Copies the currently-marked range into a new
- slot, making it a sound in it's own right. There are 15 slots maximum, and
- you will be prompted for a name for the new sound.
-
- e. Append Slot to Slot: This will append two slots together (a "slot" is
- equivalent to a sound in this instance). You will be prompted for the slot
- to append, then for the slot to append to.
-
- f. Alter Playback Speed: Just what it says. It's used to alter the
- playback period for a sound, or to set it in the case of a non-IFF sound or
- ifyou're digitizing a new sound. Move the slider gadget until the desired
- valueis shown in the numeric readout, then click the "OK!" gadget.
-
- 2. Special
-
- The Special menu includes some of the "goodies" and frills of the program,
- such as the frequency changers, the grapher and other things. Functions
- are:
-
- a. Flip current sample: Reverses current sample, making a mirror-image
- sound that is backwards from the original sound.
-
- b. Graph current range: Graphs the range shown by the START and END
- markers. The graph is scaled between 0 and 255, with 128 as the median
- value. The program does internal conversion for this, so you don't have to
- worry. This is mostly of use if you're interested in such things, or if
- you're setting the digitizer to work with a particular sound source. The
- graph loses accuracy in proportion with the size of the range graphed:
- i.e. the larger the range, the less accurate the graph.
-
- c. Create Instrument: Creating instruments is somewhat complex (not the
- program' s fault, the IFF FORMAT is complex for instruments). To create
- aninstrument will be dealt with in Section III below... This is just the
- menu choice you make to do it with.
-
- d. Freq=Freq/2: This will divide the frequency of the current sample by
- two without changing the playback period. This is done by doubling the
- sample size and interpolating. It's main use is to create octaves for
- instruments <see below> and to have fun with.
-
- e. Freq=Freq*2: Is the converse of the above, this will double the
- frequency of the current sample by removing every other sample value. Is
- mostly used in creating octaves, and for having fun.
-
- III. IFF Instruments
-
- This editor makes use of the IFF 8-bit SFVX format for sounds and
- instruments. This means that this program can be used with any IFF-based
- program that uses sounds or instruments... a growing number. Instruments
- can be created with this program as well as sampled sounds: the way to do
- this follows.
-
- 1. Iff Instrument
-
- Format
-
- A knowledge of this is necessary to understand how to create instruments.
- An IFF instrument is made up of octaves, each octave consisting of a
- single-shot sound (a sound played once at the beginning of the note) and an
- optional repeated sound (A sound that will be repeated for frequency drone
- during the length of play of the instrument). An IFF instrument must have
- at least one octave (it can have more). The octaves must be in order of
- decreasing frequency (the highest octave must be first), and each
- successive octave must be double the length of the preceding. The
- repeating parts of allthe octaves must have the same number of cycles. If
- this is all confusing, see the IFF_SND_FORMAT file for full documentation
- as put out by Electronic Arts.
-
- 2. Creating an Instrument
-
- To create a instrument using the Perfect Sound Editor, do the following:
-
- a. Make sure that all slots are clear save for the octaves (sounds)that
- will go into the instrument.
-
- b. Use the START marker on each sound to mark the repeating portion of each
- octave (move it all the way to the right if there is to be no
- repeating part, all the way to the left if it ALL repeats).
-
- c. Select "Create Instrument" under the Special menu. The sounds will be
- arranged by the program in order of decreasing frequency, and you will be
- warned if there's any variation from IFF specs (for example, if one of the
- sounds is not a multiple of 2 of the preceding, you'll get a warning,
- 'cause that usually means an odd octave). You cannot double-click on an
- instrument to play it, instead use the function keys to play each octave of
- an instrument. I hope this file helps you in your appreciation of the
- Perfect Sound editor!
